2.4%*[40-X]=4%*[40-X]如何算
2.4%*[40-X]=4%*[40-X]如何算

2.4%*[40-X]=4%*[40-X]如何算
设 40-X = k
2.4% k = 4% k
=> k = 0
=> 40 - X =0
X = 40
遇到这题就要用逻辑啦~:P

4x+x=40x x-40%x= (16x-13)/(4x-3)-(20x-24)/(4x-5)=(32x-30)/(8x-7)-(40x-43)/(8x-9)求x 解分式方程：1/X-2+1/X-6=1/X-7+1/X-11/X-2+1/X-6=1/X-7+1/X-11/(x-2)-1/(x-1)=1/(x-7)-1/(x-6)(x-1-x+2)/(x-2)(x-1)=(x-6-x+7)/(x-7)(x-6)1/(x-2)(x-1)=1/(x-7)(x-6)(x-2)(x-1)=(x-7)(x-6)x^2-3x+2=x^2-13x+4213x-3x=42-210x=40x=4 为什么要移向才能解 x-40%x-40%x=15 （4x-40）+x=420 x=? 若|x-10|=4|x-40|,则x= 解方程：x-40%x+12=x-1/4 解方程：3x-20+4x=x+40 40-2x=60-4x x等于多少? x-(x/2-40)-(x/4+60)=60求解 x-3/4x=240-x-40怎么解? x^4+x^40=237 求X x+40=2x x=? X×X+(40-X)=58 X乘以X等于40 ---------------------X=? 10x+x*x=40 (x+40%x)×85%-x=95
